Hi, any suggestions on not allowing the player to get to the edge of the field, I was thinking in that he would cross that boundary and be forced back, for example by a radiation zone alert. This way he would not reach the end of the terrain.
I am new to UE, but some things I have found, but how effective they are, or efficient, I will leave up to you to decide!
A very simple method
You can add a game actor, like a box, and stretch it over the area you want the character to not enter or pass beyond, Mak a tag called radiation and assign it with the box, you will also allow the player to pass through the object. You can also use multiple spheres, rather than one large box, allowing you more control over where they are placed and what areas are cut off.
You will also have to make sure to assign the tag as a damage type.
Or you can make a game object or objects, and when the player comes within range of the object they are transitioned back to a previous position.
